Whatever type of 4×4 off-roader you drive, and especially if that 4×4 off-roader is a Jeep, chances are there’s a skid plate kit designed to affordably protect its vital organs and other components from damage when used in challenging terrain.

The Best Spare Tire Mounting Options

Skid plates, specifically, attach to the underside of the vehicle in question—and while some are used to make a styling statement, they also have the all-important functionality of providing a physical barrier between rough terrain, and your truck, SUV or Jeep’s most vulnerable parts, including the oil pan, exhaust, radiator, fluid lines, fuel tank, and more.

Protection is also available for off-roaders who want to protect their vehicle bodies and bumpers from damage, too.

Off-road skid plates and other armor provisions come in many shapes and sizes, and with a wide range of advanced functions. Below, we’ll highlight some of your best options, across a wide range of price points.

Generally positive owner reviews round out the package, with most users reporting satisfaction with the quality, durability, ease of install and precise fitment.

CAREPAIR Bumper and Grille Guard


This bumper and grille guard won’t protect your 4×4’s oil pan or fuel tank, though it can add a high-functionality styling touch, and some added protection against impacts and damage to your vehicle’s front bumper, radiator and front-end parts. Made of heavy-duty steel and powder coated for a long and corrosion-free life, this product features a tube-shaped design and includes pre-drilled holes for fuss-free installation of popular add-on lighting provisions.

Poison Spyder Rocker Knockers


Providing tough protection for your vehicle’s vulnerable rocker panels is the name of the game for this popular pair of CNC laser-cut steel Rocker Knockers.  Built by Poison Spyder, they’re made of 3/16” plate steel and 1.5” tubing. Extra strength comes built in, thanks to the strategic use of special strengthening dimples.

Poison Spyder Extreme Duty Trans Mount Cross Member


Beef up the underside of your Jeep with this direct-fit transmission mount cross member, which replaces the much weaker (and thinner) factory hardware with a thick, bare-steel unit for superior protection against bends, dents and damage. With thick-gauge steel and strategic internal reinforcement, the mounting points of this cross member are virtually crush-proof, which helps contribute to the ‘extreme duty’ designation.

The Poison Spyder Extreme Duty Trans Mount Cross Member comes ready to paint or coat to your precise needs and tastes, and other skid plate provisions that attach to the factory cross-member will bolt straight on, thanks to this product’s use of the exact dimensions and mounting locations of the factory cross-member.

What You Should Know About Skid Plates

Do Your Homework (On a Forum): When deciding which skid plate kit might be best for your ride and how you drive it, consider doing some research from within an online owner’s forum before you buy. Whether you drive a Ford pickup, a Toyota FJ Cruiser, a Jeep Wrangler, or virtually anything else, there’s an online owner’s forum full of like-minded drivers of the same vehicle as you. Search for that forum, look for an ‘off-road’ sub-forum, use the search function, or post up questions. In many cases, online discussions between owners of the same vehicle will help point you at a frequently-favorited skid plate, as well as some tips, considerations, and possibly even owner reviews and installation videos.

Consider Professional Installation: Skid plate kits may not be the most difficult-to-install off-road accessory, though professional installation is still worth some thought. With proper tools, equipment, experience, and know-how, your local off-road shop can quickly (and properly) install the skid plate kit of your choice, leaving you with added confidence and peace of mind that the job is done right—and that your vehicle’s underside is fully protected.

Worth the Investment: Money spent on a full, high-quality skid plate kit is money well spent. Given that a single rock strike to your fuel tank, oil pan, steering, radiator, or air conditioning evaporator can cost you thousands in damage (not to mention leaving you stranded with a broken vehicle, miles from help), we recommend opting for the most highly-rated and comprehensive kit you can afford. Some skid plate products are sold as complete kits, and others allow shoppers to pick from a selection of specific protective plating implements. Consider what you drive, how you drive it, and what protection you need. As a bare minimum, consider investing in some strong protection for your vehicle’s oil pan, oil filter, radiator, transmission, and fuel tank—as unlike damage to a body panel or exhaust part, damage or puncturing of any of the above components will likely stop your excursion dead in its tracks.

Ask Questions: Given that skid plates come in numerous sizes, strengths, configurations and setups, the options are nearly limitless. Aluminum or steel? Full or partial protection? What about corrosion? Weight? Fuel economy? Should you spend a heap on a high-end skid-plate kit, or is your budget better spent on other off-road accessories and parts, like auxiliary lighting, a tire and wheel upgrade, or a winch? To help you sort through the options and wind up with the best skid plate setup for what you drive (and how you drive it) be sure to ask plenty of questions, and to deal with a reputable and knowledgeable seller who can answer them for you.

The Downsides: 
Understanding both the pros and cons of installing a skid plate setup to your 4×4 is important. Light to moderate off-roading in an off-road vehicle may not require any additional skid plating at all—or may be a great reason to consider adding some smaller, targeted protective plates, instead of a full-on kit. Is the added protection of a full skid plate kit worth the added weight, and its effects on handling, steering and fuel economy? Will the skid plate kit you’re installing make it more difficult to work on your vehicle when it’s time to service or maintain it? Like many off-road parts, skid plate kits have both pros and cons that you’ll want to understand to help make a more informed decision.
